Concept Art Practice – Sewer Turned Swamp

My initial idea for this concept art got altered into something slightly different, but the mood remains intact. This piece was meant to be a sewer scene. But my initial gut reaction (and it came very early in the artwork) was that the sewer would be too cramped to feature a menacing otherworldly creature. Likewise the upper right part of the scene would be rather empty.

Ah… the movies we may never make.
